PRESERVlNG-JAR.

SPECIFICATION forming part of Letters Patent N 0. 536,869, dated April2, 1895.

Application filed January 5, 1895. Serial No, 533,912. (No model.)

To 60% whom it may concern.-

Be it known that I, IVAR R. GILBERT, a citizen ol the United States,residing at Manchester, in the county of Hillsborough and State of NewHampshire, have invented certain new and useful Improvements inPreserving-Jars; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers merous details of said mechanism, and also it consists in theconstruction, arrangement, and combination of parts substantially aswill be hereinafter described and claimed.

In the annexed drawings illustrating my invention: Figure 1 is a sideelevation of my improved preserving jar. Fig. 2 is a vertical section ofthe same. Fig. 3 isa bottom plan view. Fig. 4 is an enlarged detail viewof a modified form of the bail support.

Like letters of reference denote like parts in all the figures of thedrawings.

A denotes the jar, which is preferably made entirely of glass. Glass ispreferred as a material, because when it is used, there is nothing tocorrode when the brine of the butter, for instance, comes in contacttherewith. The jar may be designed to contain anything that one may wishto keep from taint, or to preserve from mold and decay. The size of thejar may of course vary greatly. A convenient size is, say, one capableof holding five or ten pounds, more or less, but I cite this merely asan example. The opening or mouth of thejar I generally prefer to makesquare with the corners rounded, but I am not to be restricted to thisor any other shape. The mouth is provided with an encircling flange a.See Fig. 2. The cover B is preferably made of glass also. It is providedwith an encircling flange b, that fits down nicely overthe flange a. Arubber ring, gasket, or packingdlies under the flange b on top of thejar and around the flange a, so that an airtight joint is made when thecover is in place on the mouth of thejar. The cover B is provided with atransverse handle 0 havinga couple of finger openings 0' O,into whichthe fingers may be inserted in manipulating the cover, or inlifting thejar when the cover is fastened in the manner to be presently described.The upper edge of the handle 0 is provided with a central notch orindentation c, which is engaged by the hoop or bail H, as I shallpresently specify.

The lower end of jar A rests within a basket, or wire net, or dish,which serves to protect the jar from injury, besides affording a frameto which the closure springs for the cover may be connected. The wirescomposing this basket may be interlaced and fastened together in anydesired manner but I preferably provide a rectangularly bent wire E thatsurrounds the jar A a short distance above the bottom thereof.Underneath the bottom are two or more squarely bent wires, F and G, themembers of the square G being connected by the cross-wires g g, whilethe wires F and G are connected by the series of links ff. The wire Fand the wire E are connected together by the series of bent wires e e. Ihave given this detailed description of the construction of the basketin order to show one way in which it may be made, but I reserve theliberty of netting it in any other way. The upper edge wire E of thisbasket is provided at points diametrically opposite to each other, onopposite sides of the jar, with loops e e.

J J designate two spiral springs, which are located in verticalpositions on opposite sides of the jar A. The lower ends of thesesprings are formed with hooksj that engage theloops e, and their upperends have hooksj, that engage the ends of the bail or hoop H, whichextends over the top of the jar and its cover, and is adapted to engagethe handle O by dropping into the notch c therein, as shown in Figs. 1and 2. It will thus be seen that I provide a spring'bail which engagesthe cover and keeps it close and tight upon its seat, so that anairtight closure is made. The springs J J will .have considerablestrength, and will be capable of exerting a pressure of, say, ten ortwelve pounds. Therefore they will not only hold the cover rigidly inplace, but will hold it so firmly that the handle 0 may be used to liftthe jar about. These springs are of high efficiency in keeping the coverair-tight. If the jar or cover expands in consequence of heat, thesprings will automatically expand, and if they contract by cold, thesprings will likewise contract, and all the while they will exertsubstantially the same closing pressure on the cover. The bail Il may bereadily disengaged from the notch c and removed to one side or the otherand allowed to rest in one of the bail supports D until the user of thejar is again ready to fasten the cover. These supports D may be integralwith the jar as shown in Fig. 2, or they may have the form shown at D inFig. 4 where they have the lugs d d, and are attachable to the side ofthe jar. The springs J J may, instead of being attached to a basket asdescribed, be fastened to lugs cast on the side of the jar, in whichcase the basket may be dispensed with. Further the springs J J may bemade integral with the bail H, out of the same wire, if preferred.

Many changes in the exact construction and precise arrangement of thevarious parts may be made without departing from my invention,

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. In apreserving jar, the combination with the jar, its cover having ahandle, a basket that receives the bottom of the jar, a bail engagingthe said handle, and springs connecting the bail with the basket,substantially as described.

2. In a preserving jar, the combination with the jar, and its coverhaving an indented handie, of a bail engaging said handle, a basket thatreceives the bottom of the jar, spiral springs connecting the said bailand the basket, and hail rests on the side of the jar, substan tially asdescribed.

In testimony whereof I affix my signature in presence of two witnesses.

IVAR R. GILBERT.
